Tomey EM-4000 Specular Microscope

The Specular Microscope EM-4000 provides corneal endothelium images by using the specular optical principle with full automatic alignment. EM-4000 uses LED light source and a high-speed CCD camera to capture 16 images in series. It automatically selects and instantly displays the finest one from these images. It can perform automatic analysis as well as two manual analyses "Core method" and "L count method" with built-in software.

Wide Capturing area including peripheral.

Wide capturing area of 0.25x0.54mm can be viewed utilizing original technologies. The endothelium can be viewed in a wide area of the cornea. Having the patient fixate their eye on the fixation light enables the unit to cap­ture images at 13 points in total. The wide range of capturing positions has increased the chances of capturing images on patients with partial cornea opacity. 
A mark indicating the image capture location can be added to the icon that indicates the selected position of the fixation light. 
Central cornea thickness can be measured simultaneously. 
The estimated measurement in the ultrasound mode can also be displayed.
